T-Mobile’s latest Un-carrier Amped move lets you travel to Canada and Mexico and pretend that it’s the US, at least when it comes to your phone usage.

Mobile Without Borders allows you use your phone in Canada and Mexico just like you would in the US, including without any roaming fees. That includes calls — both to landlines and mobiles — texts and 4G LTE data usage. Also included is Music Freedom and Wi-Fi Calling, and T-Mo says that Data Stash support is coming later this year.

Any Simple Choice customer can get Mobile Without Borders. New customers will get it automatically, and existing T-Mo subscribers can get it by switching to a new Simple Choice plan over the phone, online, or in-store. If you’ve got a legacy plan that you don’t want to switch away from, you can add Mobile Without Borders for $10 per month.

In addition to revealing Mobile Without Borders, T-Mobile today gave a taste of its Q2 2015 numbers. The second quarter saw T-Mobile add nearly 2.1 million subscribers (2.072 million, to be precise), including more than 1 million branded postpaid and 178,000 branded prepaid users. T-Mo ended Q2 2015 with a total of 58.9 million subscribers. T-Mobile’s full Q2 2015 numbers will be revealed on July 30.
